iSolo® Alpha/Beta Counting System

iSolo® Alpha/Beta Counting System

Description

The CANBERRA iSolo® is a portable, firmware based, single-sample, manual, gas-less alpha/beta counter. The iSolo is designed for the analysis of air filters and most other types of alpha/beta samples. When analyzing air filters, the iSolo discriminates both radon and thoron and their progeny from transuranic and fission product materials on the air filter samples. The iSolo weighs as little than 6.5 kg in its lightest configuration. The iSolo uses a solid state silicon PIPS detector for alpha and beta detection. The iSOLO can be operated for 10 hours or more with internal batteries and is totally self contained.

Superior Counting Performance, Unparalleled System Features

The Series 5 platform is designed to count samples the way they are prepared in a laboratory. Sensible and smart, Series 5 counters provide integrated intelligence to satisfy the most demanding applications and routine analysis.

Enhanced Low Background and Productivity

Due to increasing environmental regulations to reach lower detection limits, sample count times have increased reducing the overall sample throughput in the laboratory. The Series 5 incorporates enhanced technology to reduce system background and increase sample throughput. Using an improved guard detector, the system sensitivity for high energy, cosmic background is increased, enabling the anti-coincidence circuitry to detect and reject more spurious background events.

The beta background for the Series 5 has been reduced by as much as 35% over older systems. Beta backgrounds as low as 0.5 cpm can be achieved. This means that the Series 5 family of low background counters can count twice as many samples for a given detection limit as a counter with a beta background of 1.0 cpm – impressive performance from an impressive system.

Custom Molded Shield

Using a graded shielding system, the Series 5 counts samples with more accuracy than any other low background counter.

The molded shield system provides 10 cm (4 in.) of custom molded lead surrounding the detector. The shield comprises interlocking modules which weigh no more than 27 kg (60 lb) each for safety and ease of assembly.

Series 5 LB5500 - Large Area Automatic Low Background Alpha/Beta Counting System

Series 5 LB5500 - Large Area Automatic Low Background Alpha/Beta Counting System

Description

Large Area Counting System

The Series 5 LB5500 low background alpha / beta counter offers a completely integrated, computer controlled system for maximum flexibility in analyzing larger size samples. The LB5500 is designed for counting large samples, up to 12.7 cm (5 in.) in diameter. Built on the same foundation of quality and innovation as other Series 5 systems, the LB5500 offers low background performance for applications requiring a large area counting system. The capabilities of Apex-Alpha /Beta™ Software make the LB5500 a state-of-the-art counting system that easily integrates into today’s count room. Specially designed detector windows provide the LB5500 with excellent counting efficiency exceeding current regulatory requirements.

Whether counting large area air filters or for methods requiring additional sample amounts, the LB5500 is the system of choice.

Enhanced Low Background and Productivity – Simply the Best

Due to increasing environmental regulations to reach lower detection limits, sample count times have increased reducing the overall sample throughput in the laboratory. The LB5500 incorporates enhanced technology to reduce system background and increase sample throughput. Using an improved guard detector, the system sensitivity for high energy, cosmic background is increased, enabling the anti-coincidence circuitry to detect and reject more spurious background events.

The beta background for the LB5500 has been reduced by as much as 25% over older systems. Beta backgrounds as low as 3.0 cpm can be achieved. This means that the system can count almost twice as many samples for a given detection limit as a counter with a beta background of 5.0 cpm.

Eclipse - Control and Analysis Software for S5XLB and LB5500 Systems

Description

Eclipse is the multi-tasking, Windows XP and Windows 7 compatible software application which provides analysis and control of CANBERRA Alpha/Beta counting systems. Eclipse and the Series 5 XLB together provide capabilities and features that no other manufacturer's alpha/ beta counting system can offer. For larger samples, the Series 5 LB5500 interfaces with Eclipse in a form factor that will accept samples up to five inches in diameter. Eclipse is designed for the way samples are counted in laboratories, thereby making analysis of alpha and beta samples faster and easier. Since Eclipse has been validated and verified under CANBERRA's ISO 9001 standards - you can depend on verifiable and defensible results. All of this can be achieved with one software application using CANBERRA counting instruments and Eclipse.
